Unless one is omniscient or at least enjoys some degree of clairvoyance, no one can judge others. One can see how others appear and how they are behaving, but not who they are or why they are behaving in a particular manner. For example, enlightened ones such as buddhas, bodhisattvas, and sages appear in peaceful forms and wrathful forms, but all their activities will be for serving others with love. This is why the fully enlightened Buddha said, “Apart from myself and those like me, no one can judge another person.” Source:
